Re: Problem with U2 after boxing


Hans Summers
 


Hi Keith

I'm glad it's working Ok.

If I had a pound for every time a project worked fine outside the box, and stopped working when I boxed it all up neatly. Actually it happened with my "Ultimate" a.k.a. U1. Worked fine until I put it in the box. But then: not even any display on the LCD! Then I got distracted, working on the U2... so I still don't know what happened to it!?

Belay that.


I've simply restarted it again in FSKCW mode and it seems to be working.

To say I don't understand this would be an understatement.

Right then.

My U2 has been working well for over a week so today I decided to do the boxing up thing.

After three hours of plastic panel bashing, screwing, fixing and soldering (far more time than it took to build the actual unit) I was ready to go.

Switched on and all I get is a single continuous tone. Even in normal CW mode that's it, just a tone at full power (over 0.5W on 40m with 4 x BS170s). The logic is clearly working OK because I have full control.

I've checked and double checked everything and all connections look good with no shorts or open circuits anywhere.

The only thing different is that I've connected two external switches and not removed the original two.

I can go through the menus and change the configuration with no problems and I even tried a button-down factory reset.

It looks great in the box and it'll provide a fantastic oven to keep the temperature stable but the down side is that it just doesn't work!

Has anyone experienced this same problem at all?

73 Keith, G6NHU
